3.5 Ton Excavator

Built to Work. Engineered to Last.

Big Performance. Compact Footprint.

The Big Sur 3.5-Ton Excavator combines serious digging performance, premium hydraulics and exceptional operator comfort in a compact zero-tail-swing platform. Built for contractors, property owners, landscapers and agricultural applications, it delivers the power and versatility to handle demanding work without the size and complexity of a larger machine.

Professional-Grade Diesel Power

Powered by your choice of a Yanmar 3TNV88 or Kubota D1703 diesel engine, the Big Sur 3.5-Ton delivers 24.4 HP of dependable, fuel-efficient power from two of the most respected names in compact equipment engines.

Why it matters: Proven engine technology means reliable starting, excellent torque and parts and service support you can depend on.

Over 6,800 Lbs. of Digging Force

A sophisticated load-sensing hydraulic system delivers up to 6,834 lbs. of bucket digging force, giving this compact excavator the muscle to tackle hard soil, trenching, stump removal, demolition and demanding excavation work.

With 25.6 GPM of hydraulic flow, response is quick, smooth and highly controllable.

Dig Nearly 10 Feet Deep

With a maximum digging depth of 9' 10", the Big Sur 3.5-Ton provides the reach needed for drainage, utilities, foundations, irrigation and other serious excavation projects.

Additional working range includes:

  • 18' 1" maximum digging radius

  • 16' 1" maximum digging height

  • 11' 8" maximum dumping height

Compact machine. Serious working envelope.

True Zero-Tail-Swing Design

Work confidently alongside buildings, fences, foundations and other obstacles.

The zero-tail-swing upper structure stays within the machine's footprint, dramatically reducing the risk of rear-end contact when working in confined areas.

At just 68.5 inches wide, the machine combines exceptional stability with impressive accessibility.

Side-Swing Boom for Tight-Site Precision

The side-swing boom allows the operator to excavate alongside walls, foundations and property lines without constantly repositioning the machine.

It's an enormous advantage for:

  • Utility trenching

  • Foundation work

  • Fence installation

  • Residential landscaping

  • Roadside projects

  • Confined construction sites

One Machine. Countless Jobs.

Standard auxiliary hydraulics transform the Big Sur 3.5-Ton into a true multi-purpose tool carrier.

Compatible attachments include:

  • Hydraulic breakers

  • Augers

  • Hydraulic thumbs and grapples

  • Hydraulic shears

  • Quick couplers

  • Specialty buckets and attachments

Dig. Drill. Break. Grab. Grade. Load.

One machine can handle an extraordinary range of work.

A Cab You'll Actually Want to Spend the Day In

Long days are easier in a machine designed around the operator.

The fully enclosed cab includes:

  • Air conditioning

  • Cab heating

  • Bluetooth audio

  • USB connectivity

  • High-fidelity speakers

  • Large color touchscreen display

  • Hydraulic pilot joystick controls

  • Ergonomically positioned controls

This is not a stripped-down compact excavator. It is designed to provide the comfort normally associated with considerably more expensive machines.

Smooth, Precise Pilot Controls

Full hydraulic pilot joystick controls provide smooth, predictable response for precise digging, grading and attachment operation.

Combined with the load-sensing hydraulic system, the machine delivers excellent control whether performing delicate finish work or demanding excavation.

Two-Speed Automatic Travel

Dual travel speeds of up to 2.73 MPH provide the combination of fine control and job-site mobility operators expect from professional equipment.

Automatic travel-speed adjustment helps the machine maintain performance across changing terrain and operating conditions.

Built for Tough Terrain

With 30° gradeability, generous 11.6-inch ground clearance and durable rubber tracks, the Big Sur 3.5-Ton is comfortable working across slopes, uneven ground, farms, construction sites and unimproved terrain.

Low 4.64 PSI ground pressure also helps minimize disturbance to lawns, finished surfaces and sensitive job sites.

Built to Work. Built to Last.

Critical structural areas utilize high-strength cast-steel components engineered to withstand demanding excavation and attachment loads.

The result is a compact excavator designed not simply to look impressive on the showroom floor—but to perform day after day in the field.
